They should be careful not to do too much. Since Trump is in power, he might ban them altogether from selling to China if they persist with such loophole. We know how unpredictable trump can be. So I think Ndivia should lay low for now.

Xingyao Semiconductor completes the acquisition of VIA's Tianjin packaging and testing factory
According to the "Longwan Release" WeChat account, Zhejiang Starshine Semiconductor Co., Ltd. (Starshine) has recently officially completed the acquisition of the Tianjin Packaging and Testing Factory (Tianjin VIA Electronics Co., Ltd.) under the Korean VIA Corporation (Wisol). This strategic acquisition covers the factory's production equipment, software, mature packaging system, operations and technical team, marking that Starshine Semiconductor has achieved a closed loop of the entire industry chain of "R&D design-wafer manufacturing-packaging and testing" in the field of RF filters, and has completely opened up the lifeline of localization of 5G RF front-end core components.
It is understood that South Korea's Wisol has been deeply involved in the field of surface acoustic wave filters (SAW) since 1992, and established its first overseas production base in Tianjin, China in 2009. The VIA Tianjin factory has large-scale packaging mass production capabilities and a localized supply chain system.
This time, by integrating the mature mass production system of VIA Tianjin Packaging and Testing Plant, it will form a deep collaboration with Xingyao Semiconductor's Wenzhou 5G filter wafer manufacturing base, enabling the company to have full-process independent production capabilities from wafer tape-out to high-end packaging and testing. Relying on the advantages of full industry chain integration, along with the improvement of production capacity and efficiency of Wenzhou wafer manufacturing base and Tianjin packaging plant, Xingyao Semiconductor is expected to achieve a breakthrough growth in the scale of filter mass production and significantly enhance the market competitiveness of domestic RF chips.
You don't understand, Nvidia has to do this. Jensen already said not doing this is a $50 billion dollar loss. Essentially what he's saying is he will keep trying loopholes or let the company die. There's no other options left. So it's an announcement to the world, Nvidia only lasts as long as the US government allows it to, the balls in the US government's court. Obviously from our side, we should hope Trump clamps down even more.
For those who are saying Chinese companies keep buying Nvidia so China can't catch up easily if they are stopped, that's the point. It doesn't matter if it's some what worse right now to use Chinese equipment. It can't get better unless there's more pressure on it to do so. So ironically, a full cut off which is painful, would be beneficial.
The H100 nevermind the H20 has become so cheap in China that AI training costs are a fraction of that in the US.
And that was with Biden's ban on sale to third countries.
And before any real ramp up of Chinese AI chips beyond Ascend.
Now Trump is getting rid of the 3rd party ban and the CloudMatrix is getting delivered.
What do you think is going to happen?
Jingzhou Equipment's first domestically produced G6 coating and developing equipment was delivered to a leading panel company.
Recently, the first domestically produced G6 coating and developing equipment independently developed by Jingzhou Equipment was officially moved into the production line of a leading domestic display panel company. As a key process equipment in display panel manufacturing, the successful delivery of this equipment marks a major breakthrough in my country's high-precision display panel wet process, filling the gap in domestically developed high-end coating and developing equipment, and pressing the "accelerator" for the independence of the new display industry.
Tackle core technologies and reshape the industry landscape
The coating and developing equipment is the core process of display panel manufacturing. Its precision directly affects the product yield, but its technology has long been monopolized by overseas companies, and the equipment procurement and maintenance costs remain high. With more than ten years of technological accumulation, Jingzhou Equipment has overcome core problems, reconstructed the PLC control system architecture, simplified the equipment communication level, and greatly improved the fault tolerance of the production line. After mass production, the comprehensive yield of this equipment has reached the international leading level, and the supporting intelligent operation and maintenance system can reduce maintenance costs by 25%. It is specially adapted to the characteristics of domestic production lines for in-depth customization.

TCL Huaxing supplies Lenovo Motorazr60 series folding screen, using UTG ultra-thin flexible glass.
Lenovo's moto razr 60 series foldable screen mobile phone was released in China last night, priced from 3499 yuan, and 2999 yuan after the national subsidy. After the press conference, TCL Huaxing issued a statement to "claim" the display screen of this new phone.
TCL Huaxing said that this series of products are all equipped with LTPO screens supplied by TCL Huaxing, among which the inner and outer screens of Lenovo moto razr 60 ultra are exclusively supplied by TCL Huaxing.
According to the official introduction, Lenovo's moto razr 60 series mobile phones are slim, smart, fresh and fashionable. Thanks to TCL Huaxing's use of 50um thick UTG ultra-thin flexible glass , it maintains high light transmittance while enhancing the reliability of the screen and greatly optimizing the crease. The phone adopts a 6.96-inch ultra-large inner screen design with a high resolution of 1224×2992 and a pixel density of 464ppi.
The latest generation of luminescent material technology from TCL Huaxing used in this screen supply has a 13% lower power consumption than the previous generation. Through the coordinated optimization of 8T1C LTPO technology and polarizer-free technology, not only can the widest refresh rate of intelligent adaptive reach 1-165Hz , which can accurately identify the usage scenario, but also the partition refresh technology can ensure smooth pictures while further optimizing energy consumption.
